Taiwan s South China Sea-Maritime Continent (SCS-MC) Field Campaign (2017-2019) Lead scientists: Po-Hsiung Lin (NTU), Yu-Chieng Liou (NCU/TTFRI) The Maritime Continent (MC) and South China Sea (SCS) acts as a water vapor pathway connecting the Indian and East Asian Western North Pacific monsoon during boreal summer, and connecting the powerful EA winter monsoon with the Australian summer monsoon. This proposed SCS-MC campaign focus on four major themes: Boreal winter monsoon: mid latitude-tropical interactions Boreal summer monsoon and climate variability (QBWO, BSISO, MJO) Convection Interactions in the SCS-MC area Air-Land interaction, land use, and convection over the MC Current Participating Institutes: National Taiwan University(NTU), National Central University(NCU), Academia Sinica, Chinese Culture University(CCU), Taiwan Typhoon and Flood Research Institute(TTFRI), Central Weather Bureau(CWB), Taiwan Ocean Research Institute(TORI)
